Screening results of hybridomas.

a The titers of supernatants were defined as the reciprocal of the dilution that gave an absorbance closest to 1.0. b ZEA was prepared by diluting the standard solution with PBS, mixed with equivalent supernatants, the final concentrations were 25 ng mL−1, 0 ng mL−1 were PBS containing the same content of methanol.a 上清液效价定义为使吸光度最接近1.0的稀释倍数的倒数。 b 采用磷酸盐缓冲液（PBS）稀释标准溶液制备ZEA，与等体积上清液混合，终浓度为25 ng·mL⁻¹；0 ng·mL⁻¹组为含等量甲醇的PBS。
